I had a 2400 stall in my GTA and it would flash to 2800 or so at times, depending on how much weight was in the car. If I held the brakes and pushed the pedal down the rear tires would start to overcome the brakes by about 2000rpm. In fact, I have a video if it.

211/219 duration @ .050", .500"/.525" lift, 112lsa.
stock heads, cleaned up. Did the work myself, first time. not professional work.
Hooker 2055 headers, SLP 2otL catback.
2400 stall.
running stock prom, so plenty of power left in it at that point. 0-60mph in 5 seconds flat according to the video. (timed from the first frame where the needle moves to when the needle passes the 60 mark. Let off at 115mph. Rolled into the throttle, so it wasn't a hard launch at all.
BTW, it still got 21mpg without a tune on the ECM, though it wasn't the best idle. At times it would surge, etc... A dyno tune with a wide band would have fixed it, the ecm did okay, but not great with the mods. With a tune I expect it would have been back up towards 26 to 30mpg.
